[Feature] A new "Quick Search Words" tab in options allows you to specify quick search word replacements; here you can quickly specify words that have alternate meanings when typed into the search box. Start each line with a search word, followed by = and then the replacement text. For example, if you would like to be able to type "ff" to search for "firefox" you can specify that here as "ff = firefox". This just makes it much easier to do certain simple things without using aliases.
